Subject: Crafty WCCC hardware

Finally got access to the machine we will use for the WCCC.

4 X 850 opteron (2.4ghz).
16 gigs of RAM.

Here is the "bench" result:

Total nodes: 104870200
Raw nodes per second: 8739183
Total elapsed time: 12
SMP time-to-ply measurement: 53.333333


I will post some results from time to time.  Looks like a reasonable box.  The
8-way 8048 I ran on a few months back hit around 15.5-16.0M nodes per second,
for reference...  Here is my dual xeon, for comparison:

Total nodes: 88998098
Raw nodes per second: 2119002
Total elapsed time: 42
SMP time-to-ply measurement: 15.238095

Single CPU opteron 850:

Total nodes: 71553363
Raw nodes per second: 2385112
Total elapsed time: 30
SMP time-to-ply measurement: 21.333333


Single CPU blows my 2 X 2.8 xeon away.
